    You're right. The driver assistance systems are just meant to take over and help when driver can't respond fast enough and lose control in unavoidable situations, they aren't for to show off pushing the car over its limits on public streets!..

    Sorry, maybe you're right and it's wrong to say that they are exactly same, because UCL brakes both front wheels ("bremst beim Untersteuern beide Vorderräder"), but the EUC system in the Corsa can apply braking to all wheels when necessary, so it's safe to say it's the much more developed version of UCL, as its name ("Enhanced") implies.


    Therefore, it is also wrong to say that Corsa's ESP system doesn't have Understeer Control.

    The article below is from the Opel's press-release, dated 22.08.2006.
    It's much more longer than this but I copied & pasted relevant sections only.
    I would really love to translate it to German if I could, sorry.




    The newest generation of ABS and ESP systems boasts additional functions. The Corsa’s ABS system features electronic brake force distribution, Cornering Brake Control (CBC) and Straight-Line Stability control (SLS).


    The ESP system was tuned so that it firstly gives complete control to the driver, even at very high cornering speeds, and only gradually takes over when there is danger of losing safe control of the car. The Corsa features especially dynamic performance at its cornering stability limit thanks to Enhanced Understeering Control (EUC), an ESP function: ESP controls braking individually at up to four wheels if necessary, as if the driver had a brake pedal for each wheel, to quickly stop any skidding that might occur.


    In addition to their traditional functions, the Corsa’s driver assistance systems (ABS/Anti-lock Braking System and ESP/Electronic Stability Program) can take over a range of other functions and sensitively react to particular road and driving conditions. The overview shows what these electronic control systems do and how they assist drivers in critical situations :


    Functions of ABS :


    ABS (Anti-lock Braking System)
    Prevents wheel lock-up during maximum braking, thereby insuring steering control
    If a wheel begins to lock up during braking, the ABS control unit automatically reduces braking pressure on the wheel-brake cylinder until wheel slip returns to normal.

    CBC (Cornering Brake Control)
    Optimizes braking distance and driving stability when braking in curves
    When wheel sensors register different rpm right and left in a curve, braking force on inner wheels is reduced when brake pressure is applied under the ABS limit. This creates torque that stabilizes the vehicle.

    DTC (Drag Torque Control)
    Prevents lock-up on driving wheels when clutch is engaged and during downshifting in curves
    Increases engine torque (by opening throttle valve), thus preventing wheel lock-up by engine drag torque.

    EBD (Electronic Brake Force Distribution)
    Keeps braking distance as short as possible
    The brake pressure necessary for optimum stopping distance is applied individually to each wheel.

    SLS (Straight-Line Stability control)
    Optimizes straight-ahead braking stability
    Prevents skidding when braking during straight-ahead driving, especially useful on uneven road surfaces or poorly-maintained streets. SLS identifies the driver’s desired direction of travel via the steering wheel angle and stabilizes the car with specific brake pressure application, thus keeping the vehicle on track.


    Functions of ESP

    ESP (Electronic Stability Program)
    Prevents break-away in curves.
    With the help of sensors, ESP determines rpm, steering angle, yaw velocity and lateral acceleration. This compares driver’s intentions with driving condition. Should critical driving situations occur, the system intervenes in engine electronics and with selevtice braking at up to four wheels to return vehicle to stable driving condition.

    EUC (Enhanced Understeering Control)
    Supports neutral cornering behavior.
    In an understeer situation, speed is first reduced by the throttle and then by braking up to four wheels, ensuring stable cornering behavior.

    TCPlus (Traction ControlPlus)
    Prevents wheel spin on driving wheels.
    If one of the car’s drive wheels is on solid and the other on slippery ground, one wheel will tend toward wheelspin when driving off. TCPlus automatically brakes the wheel with traction problems until the second drive wheel can transfer enough torque to drive off.




    So, EUC and UCL are exactly the same things, they had simply called it with another name in the lexicon.

    In my opinion:
    ESP: Only one of four wheels is controlled by ESP at one moment.
    ESP+: Four wheels are controlled by ESP at one moment. Also understeering will be privented.


    Yes, that's correct but it was before the Corsa D.


    The system has been developed to control four wheels individually at any moment; also with some other new features, and they named it ESP+.


    All countries get the same system, Opel makes no distinction between countries, at least regarding the ESP+. :)

    In deutschland wird auch nur ESP+ ausgeliefert (alle Modelle), im Ausland hingegen könnte sich auch nur ESP hinter verbergen...


    There are no separate versions like ESP+ or ESP.
    When a Corsa D customer checks the ESP option, his/her car comes with the ESP+.


    ESP+ is simply the name of the latest version of the system.
    The name could have been anything, for example ESP 2.0, 3.0 etc. like a software.
